Annular combustion chamber for turbomachine

摘要

The chamber has an external axial wall (2), an internal axial wall (4) and the chamber bottom (8) connecting the axial walls. The walls are multi-perforated along their length to allow reinforcement of cooling air films (D1, D2). Each wall is provided, in the upstream portion, with zones (54, 40) of perforations (38) such that cooling air is introduced with counter-flow inside the chamber.
